APPARATUS FOR THE CONTINUOUS CARBONATION 0F ALKALINE SUGAR-JUICE.

SPECIFICATION forming part of Letters Patent No. 739,702, datedSeptember 22, 1903. Application tiled November 8, 1902. Serial No.130,493. (No model.)

To all whom it may concern.:

Be it known that l, LEON NAUDET, a citizen of the Republic of France,residing at Paris, France, have invented certain new and usefulImprovements in Apparatus for the Continuous Carbonation of AlkalineSugar-Juice, of which the following isa specication.

In French Patent No. 295,906, dated .lauw ary 5, 1900, and granted toEmile Duplos and Edmund Duplos and Leon Naudet, of Paris, France, thereis described a process of and apparatus for the continuous carbonationof alkaline sugar-juice. Y

My present invention relates to an improvement in such apparatus byreason of which the operation of the Vdevice is modified and simpliedand, further, to the combination, with the carbonation vessel, of adevice which has for its object to initially determine and regulate thedegree of alkalinity of the carbonated juice delivered from theapparatus.

It is now well understood that the vertical space which a deiinitequantity of carbonated sugar-juice will occupy in the carbonation vesselwill depend upon its alkalinity, or, in other words, that'the viscosityof the carbonated juice will decrease as the alkalinity of` thesugar-juice is neutralized by the action of the acid gas employed.Consequently if means are provided which may be adjusted to determinethe level 'at which the carbonated sugar-j nice shall leave theapparatus the degree of alkalinity of the carbonated sugarjuice can beinitially determined.

The accompanying drawings will serve to illustrate my invention and inwhich similar numerals indicate like parts. A

Figure 1 is a side elevation and partial section through a pair ofcarbonating vessels and the devices forixing the level at which thecarbonated sugar-juice shall leave the apparatus. Fig. 2 is a plan vievvtaken on the line X X of Fig. 1. Fig. 3 is an enlarged view, taken atright angles to the view shown in for regulating the level Fig. 1, ofthe device at which the' carbonated sugar-juice shall leave theapparatus. Fig. l is an enlarged view of the mechanism employed forregulating the admission of the alkaline sugar-juice to the carbonationvessel. Fig. 5 is an enlarged view of the mechanism for controlling thevalve 'regulating the admission ofthe alkaline sugar-juice to thecarbonation vessel. Fig. 6 is an `enlarged view of the bottom of thecarbonation vessel.

In the drawings, 10 indicates a carbonation or treating vessel, whichmay be of any suitable size. The top of the vessel is provided with aventilator 11, through lwhich any eX- cess of acid gas (preferablycarbonio-acid gas) may find egress from the vessel; 12, a pipe throughwhich the alkaline sugar-juice (hot or cold and preferably made alkalinewith lime) is introduced and discharged into the bottom of thecarbonation vessel. Surrounding this pipe is a perforated conical screen13, and connected to the top of this screen, through a suitable coupling14, is a pipe 15, through which the acid gas is introduced into the tankunder pressure. Arranged above the perforated screen 13 is a` horizontalscreen 16. The screens 13 and 16 serve, by checking the upward ow ofthesugar-j nice and gas, topproinote an intimate mixture of thesebodies, and, further, to prevent frothy matters and scum from risingthrough the body of the sugar-juice above the screens. In the bottom ofthe carbonation vessel is a valved outlet 17, through which any depositor heavy matters may be drawn oi.

18 indicates a pipe, through which the carbonated sugar-juice may bedrawn from the carbonation vessel. The upper end of this pipe isprotected by a shield 19, which serves to prevent bodies in the form oflumps, scum, dre., from entering the pipelS. The pipe 18 is carrieddownward in the carbonation vessel and' then outward through its walland upward and connected with the interior of the tank 20 at its bottom.Situated within and carried through the tank 20 is a pipe 2l, whichserves as a discharge or outlet pipe for the carbonated sugar-juice. Theupper end of this pipe is provided with extensions 22, in which areformed slots 23, aud situated within this pipe is a short pipe 2d,arranged horizontally, onto the upper end of which are bolts 25, adaptedto move and be secured in 'the slots 23 of the extensions 22. It will beseen that by vertically adjusting the pipe 24 in the pipe 21 the levelof Vthe outlet for the carbonated sugar-juice above the bottom of thecarbonation vessel 10 and tank 20 can be varied as desired.

ICO

p 26 indicates a test-pipe connected to the bottom of the tank 2O.

Situated to the left of the carbonation vessel lO is a cylindricalvessel 27, connected at its bottom to the carbonation vessel 10 througha pipe 28. Connected to the'lower part of the pipe 2S is a test-pipe 29.Located within the vessel 27 is a float 80, which is connected to a stem31, adapted to reciprocate vertically in the guides 32, secured to theside of the carbonation-tank. Pivotally connected to the upper end ofthe stem 31 is a link 33, the lower end of which is pivotally connectedto a lever 34, secured on' shaft 35, on which is the valve 36, whichcontrols the supply of alkaline sugar-juice to the carbonation ves- Thelink 33 has in its upper and lower ends a series of holes l37 in orderthat its point of connection through the bolts 38 with the stem 31 andlever 34 may be altered, and thereby vary the initial position of thevalve 36, and thus regulatethe inflow of alkaline sugar-juice and themovement of the Valve under the action of the float 30. Secured to shaft35 is a lever 39. This lever is slotted at 40, which slot incloses thestem 31 between the stops 41. The lever 39 serves as a means formanually acting upon the stem 31 to actuate the valve 36 when desired.

The operation of my device is as follows: A definite quantity ofalkaline sugar-juice and acid gas is introduced vinto the bottom of thecarbonation vessel 10 through the pipes 12 and 15, and after a shorttime the alkalinity of the resultant sugar-juice is determined by anysuitable device. If the alkalinity of the sugar-juice is found to bethat which is desired, the top of the pipe 24 in the tank 2O is securedat the then level of the carbonated sugar-juice in the carbonationvessel 10. If, however, the alkalinity is found to be less than thatrequired, more alkaline sugar-juice is introd uced until the requiredalkalinityisobtained. Afterhavingdetermined the level for the requiredalkalinity the valve 36 in pipe 12 is adjusted to permit a definitequantity of alkaline sugar-juice to flow into the carbonation vessel ina unit of time, which alkaline sugar -juice will displace acorresponding quantity of carbonated sugar-j nice, which will flowthrough pipe 18 into tank 2O and thence through'pipe 24 out of theapparatus. This condition will prevail so long as the requiredalkalinity of the carbonated sugar-j uice is maintained, for it will bereadily seen that the level of the carbonated sugarjuice in thecarbonation vessel and tank will remain practicallyconstant so long asthe alkalinity and viscosity of the carbonated sugarjuice are constant.Should, however, a condition prevail which would result in a change ofalkalinity-as, for instance, should the sugar-juice contain more or lessalkali than is normally present or the pressure of the acid gas beincreased or decreased, &c.then a change in the level of the sugar-juicein the carbonation vessel will take place and through the float `30 `achange in the position of the valve 36 controlling the supply ofalkaline sugar-juice to the carbonation vessel. Bear ing in mind nowthat the level of the carbonated sugar-j nice in the carbonationv vesselcorresponds to its alkalinity and viscosity, it will be seen that whenthe alkalinity of the carbonated sugar-juice is increased above thenormal it is necessary to cut off or decrease the ingress into thecarbonation vessel of further alkaline sugar-juice until the acid gashas acted upon the sugar-juice in the carbonation vessel to restore thenormal alkalinity and level.v On the other hand, should the alkalinitydecrease it will be vnecessary to introduce further'alkaline sugar-juiceto create the desired balance.

In the drawings, Fig. 1, the level occupied by the pipes 24 incontiguous tanks 2O is shown to be dierent. Thisillustration was madefor the purpose of showing, rst, that the position of the pipe 24 islcapable of adjustment, and, second, to bring out the fact that twocontiguous tanks can be adjusted when supplied with sugar-juice ofdierent degrees of alkalinity to produce a sugar-juice of the samedegree of alkalinity. It will be observed that the test-pipe 26 isconnected to both of the tanks 20. This test-pipe draws from both tanks,and manifestly a sample drawn from it could be tested'in comparison withthat drawn from either of the pipes 21.
